Either the inner or outer front brake pad could be missing on a small number of the cars recalled, GM spokesman Alan Adler said. A missing brake pad could result in longer stopping distances and increase the likelihood of a crash.
GM will begin notifying owners of the recall starting on January 14, and dealers will inspect for absent brake pads and install new units if necessary. If any damage has been caused to the brake calipers or rotors, those parts will also be replaced free of charge.
The affected vehicles were built from June 2, 2011 through November 21, 2011.
